To microbes, fluids appear thick and still, and viscosity is the main force small organisms must reckon with.
对微生物来说，液体看起来粘稠而静止不动，粘稠性是小型有机体要考虑的主要因素。

There are three sections of damping force, and they are background damping force of a fluid viscosity, electric damping force of applied electric field and pressure of gas.
A simplified mechanical model of sticky soil with certain viscosity was proposed for simulating the force between the soil and corrugated bulldozing plates.
